OAR-LOCK.

Application filed July 31,

To all whom it may concern:

Be it known that I, Alonzo J. SARGENT, a citizen of the United Statesresiding at Jackson in the county of Jackson and State of lviichigan,have invented certain new and useful Improvements in Oar-Locks of whichthe following is a specification.

This invention relates to an improved detachable oar lock and has as oneof its principal objects to provide a device of this character which maybe conveniently carried about and to this end will be provided withelements which may be folded so that the device will occupy a minimumspace.

The invention has as a further object in this connection to provide adevice having foldabie supporting arms but wherein said arms will, whenin active position, be locked against movement.

And a still further object of the invention is to provide a device whichmay be readily attached to or detached from the gunwale of a boat andadapted, when in position, to support an oar stirrup above the gunwaleso that such stirrup will not wear against the gunwale.

Other and incidental objects will appear hereinafter.

In the drawings:

Figure 1 is a plan view showing my improved device applied to thegunwale of a boat, the gunwale being conventionally illustrated,

Fig. 2 is a perspective view showing the device detached,

Fig. 3 is a fragmentary sectional view taken on the line 3 3 of Fig. 1,and

Fig. at is a fragmentary sectional view 7 taken at substantially rightangles to Fig. 3, centrally through the device.

Fig. is a fragmentary view of the top most portion of supporting arm 14.

In carrying the invention into effect, my improved device is formed witha cylindrical stirrup socket or barrel 10 from opposite sides of whichproject pairs of spaced lugs, the uppermost of which are indicated at 11while the lower lugs of said pairs are indicated at 12. The uppermostlugs 11 are somewhat thicker than the lower lugs and formed in the lugs11 are, medial alined slots 13 opening through the outer ends of thelugs and extending radially with respect to the socket 10. In thisconnection, it is to be observed that the socket is open at its ends.Swingingly mounted upon the socket are Specification of Letters Patent.Patqented Mal 34), 1920.

Serial 13f 0. 314,454.

standing from the uppermost of the lugs 16 are ribs 17 and removablyengaging through the lugs of the socket and the lugs 16 of said arms arepivot pins 18 detachably and swingingly connecting the arms withthesocket.

Integrally formed on the socket at substantially right angles to theplane of the lugs 11 and 12 are clamping arms 19 and 20 respectively.ihese arms curve d0wn wardly and inwardly beneath the socket and formedon the inner end of the arm 19 is a laterally enlarged head 21. At itslower end, the arm 20 carries a cylindrical head 22 through which isthreaded a clamp screw 23 and swiveled upon the inner end of said screwis a clamping plate'24 confronting the head 21 of the arm 19. Formed onthe socket at opposite sides of the arm 19 are stop lugs 25 and formedon the lowermost of the lugs 16 of the arms 14 are stop lugs 26 adaptedto coact with the lugs 25 for limiting the arms in their outwardswinging movement to alined position.

It is now to be observed that the ribs 17 0f the arms 14 are adapted toengage within the slots 13 for locking the arms in alined activeposition extending at opposite sides of the stirrup socket 10.Consequently, the device may then, as shown in Fig. 1, be fitted uponthe gunwale of a boat to engage the arms with the upper edge of saidgunwale. In this figure the gunwale of a boat has been conventionallyillustrated at 27. The arms will thus support the device upon thegunwale in such position that the head 21 of the arm 19 will confrontthe outer face of the gunwale while the plate 24 upon the clamping screw23 will confront the inner face of the gunwale. Accordingly, theclamping screw may be operated for securely clamping the device upon thegun- Wale. The socket is adapted to carry any conventional type of oarstirrup as conventionally shown at 28 in the drawings. The shank of thestirrup is rotatably fitted through the socket in the usual manner, and

of the stirrup socket for supporting the socket spaced above the upperedge of the gunwale so that the shank of the stirrup w1ll not contactwith the gunwale to wear thereagainst. Furthermore, it is to beparticularly noted that since, when the arms l l are in active positionthey are locked against swinging movement, lateral displacement of thearms from engagement with the gunwale will be prevented. I accordinglyprovide a device which, as will be at once appreciated, may be readilyattached to the gunwale of substantially any conventional type oi? rowboat and which will provide a firm support for an oar. If desired, thearm 19 may be provided with spaced keeper lugs 30 for removablyreceiving, as suggested in dotted lines in Fig. 3, the needle of a fishstringer. In this way a string of fish may be allowed to trail in thewater while, at the same time, being conveniently connected with theboat.

Particular attention is now directed to the fact that the arms 14 aremounted to move vertically upon the pivot pins 18;

Consequently, when the device is detached, the arms-will normally dropdownwardly upon said pivot pins to disengage the lugs 17 from within theslots 13. Thus, the arms may be folded inwardly to lie along the sidesof the arm 20, so that the device will occupy a minimum space andaccordingly may be easily carried about. I, therefore, provide aparticularly convenient type of portable oar lock.

Having thus described the invention, what is claimed as new is:

1. A device of the class described including an open-ended stirrupsocket, supporting arms extending downwardly from said socket andterminating below the inner end walo for supporting the inner end of thesocket above the gunwale, clamping arms extending from the socket atopposite sides of the gunwale, and clamping means adjustable upon one ofsaid arms to cooperate with the other for engagement with the gunwale toconnect the device with the boat.

3. A device of the character described including an open-ended stirrupsocket, arms extending from the socket and terminating below the innerend thereof forsupporting the inner end or" the socket above the planeof the free ends of said arms, clamping arms projecting from the socketand terminating in a plane below the free extremities of said Iirstmentioned arms, and clamping means carried by one of said clamping armsand adjustable thereon to coeperate with the other for connecting thedevice with a boat.

1-. A device of the character described in? cluding a stirrup socket,supporting arms swinginglv connected thereto, and means for connectingthe device with a boat.

5. A device of the character described including a stirrup socket,supporting arms swingingly connected thereto, means for locking the saidarms in active position, and means for connecting the device to a boat.

6. A device of the character described in cluding a stirrup socket,supporting arms swingingly connected thereto, coacting means carried bysaid arms and the socket respectively for locking the arms in activeposition, and means for connecting the de-' vice with a boat.

7. A device of the character described including a stirrup socket, lugscarried thereby and provided with slots, arms swingingly connected withthe socket and provided with ribs engageable in said slots for lockingthe arms in active position, and means for connecting the device with aboat.

8. A device of the character described including a stirrup socket, pairsof lugs carried thereby, supporting arms for the socket, pivot pinsswingingly connecting the arms with said pairs of lugs, certain of saidlugs being provided with slots, ribs carried by the arms, the arms beingmovable longitudinally of said pivot pins to engage the lugs thereofwithin said slots for locking the arms in active position, and means forconnecting the device witha boat.

9. A device of the character described, including a stirrup socket,supporting arms swinginglyconnected thereto, means for connecting thedevice with a boat, and means for limiting the arms in their swingingmovement to active position.

10. A device of the character described in cluding a stirrup socketprovided with lugs, supporting arms swingingly connected to the socketand provided with lugs engage able with the first lugs for limiting thearms in their swinging movement to active position, and means forconnecting the device with a boat.

In testimony whereof I affix my signature.
